Fiber-based wearable sensors for bio-medical monitoring

In a recent study, Prof. Rui Min and collaborators published their paper in the journal of <italic>Opto-Electronic Science</italic> that is entitled "Smart photonic wristband for pulse wave monitoring". The paper introduces novel realization of a sensor that uses a polymer optical multi-mode fiber to sense pulse wave bio-signal from a wrist by analyzing the specklegram measured at the output of the fiber. Applying machine learning techniques over the pulse wave signal allowed medical diagnostics and recognizing different gestures with accuracy rate of 95%.
